If you want to compare apples to apples:

unjar the swt and jface files (this will make a directory structure, find 
out how much space that takes up). Jar files are compressed.

Compile DWT and D JFace into libraries.

Compare those sizes.

The built executables include tango/phobos, so you cannot compare that 
version, unless you want to add in the java runtime jar files :)

D has some reflection information through the typeinfo classes, so I would 
expect the uncompressed sizes to be roughly equivalent.

Once D is natively using DLL/.so to store the runtime, executable sizes 
should go way down.
